PIPE-STEM.

Willy Application filed January 19, 1916.

To all whom it may concern:

Be it known that I, EDWARD H. Srnorrr, a citizen of the United States, residing at Manitowoc, in the county of Manitowoc and State of Wisconsin, have invented cer tain new and useful Improvements in Pipe- Stems, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved pipe stem, and has for its primary object to provide a stem for tobacco pipes which will not absorb saliva or nicotin, or become clogged with tobacco and require frequent cleaning.

It is a more particular object of the inven tion to provide av pipe stem constructed of aluminum, said stem being slightly tapered at one end and adapted to be fitted into the opening in the pipe bowl communicating with the bore thereof, said end of the stem having an internal flange formed thereon to reduce the smoke passage or con duit at its inner end and prevent tobacco finding its way to the interior of the stem and clogging the same.

It is another and important object of the invention to provide a metallic pipe stem which will be very light in weight and from which obstructions be readily removed, it being possible to thoroughly clean the bore of the stem by immersing and washing the same in benzene, gasolene, or the like, so that all nicotin is removed therefrom and the same kept in a thoroughly sanitary condition.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a sectional view through a pipe provided with my improved stem; and

Fig. 2 is a perspective view of the pipe stem removed.

Referring in detail to the drawing, 5 designates the bowl of the pipe which may be of briar wood, corn cob, clay, meersohaum, or any other material usually provided for this purpose. The bowl of the pipe is formed adjacent to its base with an opening indicated at 6 in one side thereof, which communicates with the tobacco chamber or bore of the bowl. This opening Specification of Letters Patent.

slightly flares or increases in diameter from lar flange 9, thereby reducing the entrance 4 to the bore of the stem, said flange 9 being substantially perpendicular to the axial center of the stem 7. The tapering end S of the pipe stem is adapted to be fitted. into the opening 6 of the pipe bowl and forced into tight frictional engagement with the walls of said opening. It is to be observed that the taper of the opening 6 in the bowl 5 and the taper 8 of the stem serves to limit the insertion of the stem 7 so that when in applied position the inner end of the stem 7 and the flange 9 thereof are flush with the wall of the bowl. The other or outer end of the stem is gradually flared or increased in diameter. as shown at 10, and upon the same the rubber sleeve or mouth piece 11 is fitted and tightly held in frictional. engagement thereon by the inherent resiliency of the mouth piece. This mouth piece prevents undue compression or bending of the end of the stem when the teeth are closed thereon.

From the forgoing description, taken in connection with the accompanying drawing, the construction, manner of use and several advantages of the invention will be clearly and fully understood. As the same is constructed of aluminum, it will not absorb saliva or nicotin entering the bore thereof. and if particles of tobacco should collect in the reduced entrance to the stem, the same may be detached from the bowl and such tobacco particles readily removed by the use of a pencil point or other convenient element so that they will fall through the bore of the stem. It is thus unnecessary to use the common type of pipe cleaners such as brushes which are relatively expensive. The pipe stem may also be placed in boiling water without injury thereto, or may be cleaned with gasolene or kesosene, and subsequently thoroughly dried. As the stem is non-absorbent, no odor will remain.-

It is apparent, of course that my improved pipe stem may be made in various lengths and of other shapes than that shown in the drawing and I, therefore, reserve the privilege of making all such legitimate changes in these respects as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is As a new article of manufacture a pipe stem comprising an elongated tubular metallic body, the insertion end of the stem being provided with an inwardly directed annular flange disposed substantially perpendicular to the axis of the stem, the month end of the stem being flared, the por' tion of the insertion end of the stem immediately adjacent the flange being tapered.

In testimony whereof I hereunto aifix my signature in the presence of two witnesses.
